The absorbent article 9 in the packaging bag 3 is taken out from the opening 312. The used absorbent article is removed from the wearer, and a new absorbent article 9 taken out from the packaging bag 3 is attached to the wearer. The used absorbent article is folded and accommodated in an empty packaging bag 3.

  When the used absorbent article is accommodated, first, the vicinity of the tip 355 of the second handle forming portion 354 of the handle forming portion 351 shown in FIG. 4 is gripped, and the second handle forming portion 354 becomes a bag. By pulling the portion 31 away from the second packaging sheet member 36, the adhesive treatment surface 356 of the second handle forming portion 354 becomes the bag portion 31 and the first handle forming portion 353 as shown in FIG. It peels from the easy peeling process surface 357. As a result, the blocking portion 358 is separated from the plurality of vent holes 314, and the space in the bag portion 31 (that is, the space that is to become the accommodation space 313) communicates with the outside via the vent holes 314. In FIG. 5, illustration of the absorbent article in the packaging bag 3 is omitted (the same applies to FIGS. 6 and 7).

  In the packaging bag 3, the blocking portion 358 can be easily peeled from the vicinity of the vent hole 314 by performing an easy peeling process in the vicinity of the vent hole 314 of the bag portion 31. In the second handle forming portion 354, only the closing portion 358 covering the vicinity of the vent hole 314 may be peeled off from the bag portion 31 so that the vent hole 314 is exposed.

  Subsequently, after the used absorbent article is put into the bag part 31 through the opening 312, the male part 331 and the female part 332 of the wire fastener 33 are engaged with each other, whereby the opening 312 is sealed. Thus, an accommodation space 313 is formed. As described above, the accommodation space 313 communicates with the outside via the vent hole 314. Next, the packaging bag 3 is placed on a flat surface such as a desk so that the front surface 11 of the packaging bag 3 is in contact with the surface, and the rear surface 12 of the packaging bag 3 is pressed toward the front surface 11. Thereby, the air in the accommodation space 313 is pushed out to the outside through the vent hole 314. The air may be pushed out of the accommodation space 313 by pressing the front surface 11 and the rear surface 12 toward each other with the packaging bag 3 sandwiched between both hands.

  And the adhesion processing surface of the 2nd handle formation part 354 of the handle formation part 351 in the state by which the packaging bag 3 was pressed (namely, the state in which most of the air in the accommodation space 313 was pushed outside). 356 is affixed to the first handle forming portion 353 and the easy-release treatment surface 357 of the bag portion 31, and the plurality of vent holes 314 are closed by the closing portions 358. Thereby, the communication between the accommodation space 313 and the outside is cut off, and the used absorbent article is sealed in the accommodation space 313. In the packaging body 1, the housing space 313 is sealed, so that the smell of excrement can be prevented from leaking from the used absorbent article to the outside of the packaging bag 3.

  In addition, after the used absorbent article is put in the bag part 31 without first removing the blocking part 358 from the bag part 31, the peeling of the blocking part 358 from the bag part 31 and the wire fastener 33 are performed. The opening 312 may be sealed in random order, and then the ventilation hole 314 may be closed by the closing portion 358 to seal the packaging bag 3. Moreover, after a new absorbent article other than a used absorbent article is accommodated in the packaging bag 3, the packaging bag 3 may be sealed in the same procedure as described above.

  As described above, when the stored items such as used absorbent articles are stored in the opened packaging bag 3, the air in the storage space 313 is pushed out through the vents 314, thereby opening the opening 312. Compared with the case where air is pushed out, the air in the accommodation space 313 can be pushed out easily, and the packaging bag 3 and the packaging body 1 can be downsized. And the shape of the package bag 3 and the package body 1 which were reduced in size can be maintained by obstruct | occluding the vent hole 314 with the obstruction | occlusion part 358. FIG.

  In addition, since the closing portion 358 is a part of the handle portion 32 that is continuous with the bag portion 31, the structure of the packaging bag 3 is simplified as compared with the case where the closing portion is another member independent of the bag portion. can do. As a result, the manufacturing cost of the packaging bag 3 can be reduced. Furthermore, since the bag part 31 is soft and the overall rigidity is substantially the same except for the joint part between the first packaging sheet member 35 and the second packaging sheet member 36, the bag part 31 can be seen from any part of the bag part 31 in the accommodation space 313. Air can be easily pushed out toward the vent hole 314.

  In the packaging bag 3, as shown in FIG. 6, when the vent hole 314 is closed, between the above-described folding position 352 (indicated by a two-dot chain line in FIG. 6) and the upper end portion 315 of the bag portion 31. The handle forming part 351 may be folded at another folding position 359. In this case, the plurality of vent holes 314 are provided between the tip 355 of the handle forming portion 351 and the folding position 359, more specifically, the original blocking portion 358 of the second handle forming portion 354 (ie, before opening). The closed portion in the package 1) is closed by a portion between the folding position 359. Thereby, the packaging bag 3 and the package 1 in which the opening 312 is sealed by the wire fastener 33 can be further reduced in size.

  When the handle forming unit 351 is folded at the folding position 359, the packaging bag 3 may be provided with another weak line 3511 in the handle forming unit 351 as shown in FIG. The fragile line 3511 is a straight line arranged substantially parallel to the left-right direction between the tip 355 of the handle forming portion 351 and the portion covering the vent hole 314, and is broken so that the handle forming portion 351 is broken. The site | part by the side of the front-end | tip 355 is isolate | separated. Thereby, the length of the site | part folded in the folding position 359 of the handle formation part 351 can be shortened, and the length of the site | part which overlaps the bag part 31 of the handle formation part 351 can be shortened. As a result, a part of the handle forming portion 351 stacked on the bag portion 31 is prevented from being caught and peeled, and the handling of the packaging bag 3 and the package 1 can be facilitated.
